    Looking for a bit of help here.
    My 09 S3 Sportback is losing power in 4th 5th and 6th gear between 3000-4000rpm and the revs dip for about a second, this is when the foots to the floor! After plugging it in the fault was reading a misfire on cylinder 2, so promptly swapped over the coil pack from cylinder 2 to 1. The misfire was now on 1 so went to Audi bought a new coil pack and swapped with the the one giving the misfire.
    The problem had not been solved.....and I haven't use of the Vagcom at present. Do I change the other 3 or is this not the solution to the problem? Would appreciate some advice if anyone could help me!!

    Changed the other 3 coil packs.....problem still there only at a lower rev range????
    Think I'll change the spark plugs see if this solves it.
    ANY ideas welcome!
